For the first time since the Clinton administration, the House of Representatives passes significant gun-control legislation.
The measure requires background checks for virtually all firearms sales in the US.
The vote was 240 yeas and 190 nays and it passed without any objections.
Right now licensed gun dealers have to perform background checks to sell a weapon but unlicensed sellers don’t have to.
This bill closes that loophole.
Supporters of the bill say it will reduce gun violence but critics disagree.
The bill now heads to the Senate, where it is not expected to pass in the Republican-led chamber.
